121-OR: Safety, Tolerability, and Metabolic Effects of Once-Weekly GL0034 (Utreglutide) in Individuals with Obesity—A Multiple Ascending Dose Study

Introduction & Objective: GL0034 (GL), a once weekly glucagon-like peptide 1 receptor agonist, previously demonstrated significant reductions in body weight (BW) up to Day 22 in a single ascending dose study in individuals with obesity. This phase 1 study assessed the safety, tolerability and metabolic effects of GL after multiple ascending doses. Methods: Individuals with BMI ≥28 kg/m2 (N=24) were randomized (9:3) to subcutaneous GL, fixed doses (4 × 680 µg; cohort 1); or increasing doses (680, 900, 1520, 2000 µg; cohort 2) or placebo, once weekly for four weeks. Safety, tolerability and key metabolic parameters were assessed. Results: Most common adverse events (AE) were gastrointestinal (GI) with dose-dependent nausea, decreased appetite and vomiting. One individual with a GI related serious AE rapidly recovered upon treatment with intravenous rehydration. On Day 23, reduction was observed in all parameters from baseline (BL) with significant reductions in glucose area under the curve and HbA1c in both groups. In cohorts 1 & 2, BW reduction versus BL was 2.9 kg and 4.6 kg respectively on Day 29 (Table). Conclusions: In individuals with obesity, once weekly GL dosing for four weeks, demonstrated clinically relevant reductions in glucose, insulin, HbA1c, lipids and BW with an overall good tolerability.
